Hey! I'm using a Xperia XZ F8332 and I have unlocked the bootloader and installed TWRP. But I deleted it by installing a stock ROM because I failed to install android 9 and root my device. But now I have a problem and it is my bootloader is unlocked and every time I reboot my phone I see a note saying "Your device can't be trusted" and it's so annoying. I'm here to ask : Is there anyway to lock the bootloader? And How?
Thank you.
